Application filed March 6, 1926. Serial No. 22,894;

My invention relates to apparatus for purifying oil and particularlyv to apparatus of this character utilized in the oil fields for purifying crude petroleum. The objects of the invention are to effect a satisfactory purification with simple and inexpensive apparatus that requires only a minimum of fuel for satisfactory operation. I

The annexed drawings and the following description set forth in detail certain means embodying my invention, uch means consti: tuting, however, only one of the several forms in which the principle of the invention may be embodied.

In saidannexed drawings:

Figure 1 represents a side elevation of my improved oil-purifying apparatus, together with a broken elevation of a standard oil tank or reservoir;

'Figure 2 is a vertical section, taken in the plane indicated by the line 11-11, Fig

ure 1; and

Figure 3 is an enlarged sectional view, taken in the area of Figure 1, indicated by A 7 Referring to the annexed drawings in which the several elements are, denoted by the same respective ordinals in the 'diflerent views, I indicate a fire box by the ordinal 1 adapted to be heated by any suitable means available in the field where such apparatus is operated, the heating means herein being illustrated as a gas burner 2. If no gas is available, the fire box 1 might be heated by crude oil or any other available fuel. Welded to this fire box 1 and surrounding the latter, and spacedtherefrom, as plarnly shown in the accompanying drawing, s a jacket 3 which provides a space 3' utilized for the water heating chamber, as hereinafter fully described. vWelded to the jacket 3, preferably respectively. near the top and bottom of the same, the jacket 3 and fire box 1 preferablybeing set at a 45 angle, are a pair of collars 4 and 5 communicating with a pair of nipples 6 and 7 respectively,

which in turn communicate respectively with.

a pair of Ts 8 and 9 respectively. The T 9 communicates with nipple 10 and also with nip le sections 16, 18, and 20 through the me ium of the check valve 15, a union 17 and a stop cock 19, all as plainly shown in Figure 1. The other end of the nipple20 is adapted to communicate with oil reservoir 21 intermediate the bottom of the reservoir and the normal water line which is indicated by the ordinal 22. This oil reservoir is illustrated as of standard construction which would be normally about a hundred barrel oil tank. The T 8 communicates with an ll. 11, which in turn communicates .with a nipple 12, and the latter in turn communi cateswith an l. 13 which is contained within the upper end of the fire box 1, the nipple 12 intersecting the wall of the fire box, as

plainly shown in Figure 2. Telescopically arranged with the top of the fire box 1, is a pipe '23 adapted toserve as a smoke-stack, the top L of the; fire box being bent into substantially avertical position, as plainly shown in Figure 2, The L 13. communicates with a stand-pipe 14 contained within the smoke-stack 23, and which at the top,

through the medium of an L 24 and a'bushmg 25, communicates with a substantially horizontally-arranged pipe 26 which is surrounded by a spaced jacket 27 and connects at its other end, through the medium .of an L 28, with a depending pipe 29 of a length sufiicient to reach below the oil line in the tank 21.

For the purposes of illustration, I shall give some dimension illustrating what the capacity of the different elements might be to give satisfactory operation. For instance,

the fire box 1 and jacket 3 might be 8 inches I over-all diameter, of which the fire box is 5% inches and the space 3' surrounding the same is 1 inches. The collars 4 and 5 @are 2 inch collars, the nipples 6, 7, 10, 12, 20, etc., 2 inch nipples, the Us 13 and 24, 2 inch Us, the pipes 26, and 29, 1 inch pipes, the.

L 28, a 1 inch L, and pipe 14 and spaced pipe or jacket 27 2 inch pipes. I

It is well known to those skilled in the art that water in crude petroleum filters to the bottom of the tank 21, as indicated by the water line 22. The urpose of the 'invention is to remove the impurities, such as fresh and salt water, foreign matters such as mud, etc., and this is accomplished by heating the oil. The particular apparatus which I have described and which is shown in the accompanying drawing, draws water from the bottom of the tank 21 and passes it I tothe chamber 3' where it is heated and passe up through the conduits 8, 11, 12, 14, etc., to the horizontal pipes 26 whence it asses into the oil and heats the same as it filters. down to the water area indicated by the line '22. The arrangement of the water jacket 3 around the outside of the fire box 1 requires a comparatively small amount of fuel to effect this circulation of steam and i the water, however, is not quick enough to precipitate the salt out of the oil before circulation has taken lace. So soon as the burner 2 is shut off, it is possible to commence drawing off the purified oil through the outlet 31. The heavy impurities and t e water are drawn. off through the sludge drain 32.

I wish also to oint out that the connec- "tions used for di erent arts of the apparatus can be of standard sizes and such as are commonly found in the outfits of oil well 3 operators.

means of continuing the nipple 12 into asses u through y the stand-pipe 14 which the smoke-stack 23, I ma e use 0 the heat *in the smoke-stack and thus utilize substanmeans of the jacket 27 surrounding the transfer pipe 26, I also, protect the heated tially all of the heat from the burner 2. By

-fluid from the cold and a further savin of heat is effected b extending the depen in 'ipe 29 down he ow the surface of the o in .the tank 21, thereby making unnecessary the passage of the heated fluid through cold air.

The particular location of the upper transfer pipe 26, and the lower pipe, comprised of the nipples 10, 16, 18, and 20, is not limited to the exact location shown in the accompanying' drawing but is flexible within the limits of having the upper pipe communicate with the tank 21 ad acent the upper oil line and having the lower pipe communicate with the oil tank 21 within the water area. Also, it would be perfectly feasible to utilize a plurality of these transfer pipes in-,

stead of limitin the same, as shown in the accompanying rawing, and one lower pipe.

It will be perceived that two supporting le 30 are connected with the acket 3, w ich legs are adapted to co-operate with to one upper pipe the bottom of the burner 2 to form three supports for the smoke-stack and connected elements.
